Ohm Walsh speakers are known for their unique design, which uses a concentric driver configuration to produce sound. This design is patented by Ohm Acoustics and is not used by many other speaker manufacturers.

However, there are a few other speaker manufacturers that have developed similar designs that use a concentric driver configuration, including:

• Silverline Audio: Silverline Audio's Prelude speakers also use a concentric driver design, and are known for their detailed and accurate sound reproduction.

• Tannoy: Tannoy's Dual Concentric speakers also use a concentric driver design, which is renowned for its ability to produce a wide, stable soundstage and accurate imaging.
